What to expect at Cal Auto Service

Cal Auto Service is licensed by the Bureau of Automotive Repair as a Test & Repair smog station in Santa Ana, so it can run the inspection and, if your car fails, diagnose and fix it in the same shop. It is not STAR certified, so if your DMV renewal notice says "STAR Station Required" you will need a different station.

Walk-ins are welcome. Most smog checks take 15 to 30 minutes, and most visits are closer to 20.

What to bring

  • Your registration or DMV renewal notice

    It says whether the car needs a STAR station.

  • The car, with the check engine light off

    On a 2000-or-newer car, a lit check engine light fails the test on its own.

  • A way to pay

    The $8.25 state certificate is paid on top of the test when the car passes, unless the station's price or coupon includes it.

What if I fail?

  • Cal Auto Service can diagnose and repair the problem in the same shop, then retest the car.
  • Each station sets its own retest price, so ask before the first test.
  • BAR's Consumer Assistance Program pays up to $1,450 toward emissions repairs for income-eligible owners.
